T CZZZ whom, it muy concern,.-

" Be it known that we, MILES JnNNINGs and JOHN H. J ENNINGs, citizens ofthe United States, and residents of Elizabeth City, in the county ofPasquotanl and State of North Carolina, have made certain new and usefulImprovements in Cultivators, of which the following is a speciiication.

This invention is an improvement in cultivators, and especially instraddle-row cultivators, and has for an object, among others, toprovide a novel construction of beam and of devices for supporting thesame so the different sections of the beams can be readily adjusted inorder to set the plows in any desired relation; and the inventionconsists in certain novel constructions and combinations of parts, aswill be hereinafter described and claimed.

In the drawings, Figure l is a perspective view of a cultivatorembodyingl our invention. Fig. 2 is a detail perspective view of aportion of the handle-frame. Fig. 3 is a top plan View of thecultivator. Fig. 4 is a detail perspective view of the clamping devicesfor the plows and for the wheel-standards. Eig. 5 is a detailperspective view illustrating the devices i'or securing' the lateralarms of the arches in connect-ion with the beams, and Fig. G is a detailsection on about line 6 6 of Fig. l.

The cultivator,as shown, comprises the front arch A, the rear arch B,andthe beams C at the opposite sides ot' the implement. The arches A andB are formed, respectively, with the top bars A B', the side arms A2 B2,and the lateral arms A:i B3, said lateral arms being connected with thebeams by the devices presently described. The handle is formed with thebars C vand the handle-frame D, having the side bars D secured to thehandles C' and the cross bar D2 slotted longitudinally at vits middle at(Z to receive the bolt E, which'passes through the top bar B of the archB, thence through the slot (Z, and then through an openingin the clasp Eand receives the nut (Z. The clasp F over-lies the handle-frame and isprovided at its ends with depending lugs f, which extend down alongsidethe handle-frame and the top bar B oi' the arch and braces thehandle-frame in connection with the arch and at the same time permitsthe adjustment of the handle-frame laterally to any desired eX- tent.

The draft connection, which may be a pole G, as shown, has the arms H,which spread apart at their rear ends and are connected with the lowerends of the sides A2 of the arch A. This connection is preferablyeffected by means of the brackets I, provided at their upper ends withlugs I', fitting on opposite sides of the uprights A2, bolted near saidends at J to the said uprights A2 and having the arms H bolted to thesaid members at J near their lower ends'. This forms a convenientconnection for the draft devices and permits the latter to be arrangedbelow the lateral arms A3 of the front arch, as will be understood fromFig. l of the drawings. The beams C are secured to the lateral arms ofthe front and rear arches and are alike except that they are rights andlefts, as will be understood from Figs. l and 3 of the drawings, so thatthe description of one of the beams and the parts connected therewithwill answer for both.

VThe beam C comprises the front section C, the rear section C2, theconnecting-bar C3, and the segment C4, by which to secure the front andrear sections C and C2 in any desired adjustment. The front and rearsections are composed of bars of metal bent upon themselves at theirmiddles at one end and lapping at their inner or adjacent ends at 2 uponthe bar C3, to which they are secured by the bolts 3 and 4, so the saidsections Cl and C2 may be swung to any desired adjustment relatively toeach other so that they may be brought into alinement with each other orat any suitable angle within the range of the adjust? ment. By thismeans the front and rear sections can be adjusted inwardly or outwardly,or one inwardly and the other outwardly, to any desired extent in orderto secure the arrangement of the plows presently described to run in anylines desired. This is specially important in cultivatingdiferent cropswhere they may be planted in rows spaced different distances or where itmay be desired to run the plows nearer or farther from the growingplants for any desired purpose. In order to secure the sections C and(J2 in any desired adjustment, we provide the segment C1, which may besecured pivotally at one end by the bolt 4 to the inner end of one ofthe beamsections and swing at its free end along the other beam-sectionand be secured to the latter when the parts are set to any desiredposition by means ot' the bolt as will be understood from Fig. 1 of thedrawings. It may be preferred in some instances to tooth or roughen thesegment at 6 on opposite sides ot' its bolt-slot 7 in order to give abetter hold in clamping the segment in the desired position. By thedescribed construction by the use of an ordinary wrench the nuts may bereadily loosened .and the beam-sections set to any desired position andfirmly secured in such position.

The front arch has its lateral arms secured to the front beam-sections,and the lateral arms of the rear arch are secured to the rear sectionsot' the opposite beams, and the connection is effected by means whichpermit of the adjustment oi' the beam-sections along' the said arms insecuring the diierent adjustments of the beams. As shown, the arch-armsare secured to the beam-sections by the bolts K, having eyes K',receiving the arms A3 and fitting in recessed. blocks L, resting uponthe top ot' the bca1n-section,a nut K2 turning on the bolt between theupper and lower bars of the beam, as will be understood f rom Fig. 6 ofthe drawings. The recessed block L has the recesses L in its upper faceto receive the eye K and is notched at L2 in the opposite walls ot' saidrecesses to receive the arms of the arch, as shown in Fig. 5.

Each of the beam-sections carries astandard M of a shovel M, which maybe of any suitable i'orm, and the front ends of the beams are supportedby the wheels N, having' standards N connected with the beams, and thesaid standards M and N are connected with the beams by similar devices,which are shown in detail in Fig. et of the drawings and applied for usein Figs. 1 and 3 and consist of a block O, an eyebolt P, a bearing-plateQ, and a nut R. The block O is grooved vertically in one face at O forthe standard and has in said face a recess O2 for the eye P of the boltP, which latter embraces the standard and draws the same iirmly into thegroove O of the block O when secured, as shown in Figs. 1 and 3. rlheface of the block O opposite the groove O is recessed at O3 to lit thebeam, and the bolt P extends through the block O, thence between theupper and lower bars ot' the beam, (see Fig'. 1,) thence through thebearing-plate Q, on the opposite side of the beam from the block O, andreceives the nut R, which turns up against the bearing-plate Q, as willbe understood from Figs. 1 and 3 of the drawings. By this means thestandards may be secured in any desired vertical zuljustment, and thesecuring devices may be adjusted along the beam in order to set thestandards at any desired point along the said beams as may be desired inthe use or' the implement.

From the foregoing description it will be understood that we provide animplement in which the beams are composed of sections which may beadjusted relatively to each other and also adjustable along the arms ot'the front and rear arches so the shovels can be set to any desiredposition and those on the same side of the implement be caused to rundirectly in line with each other, or the front and rear shovels may beset to any desired relative position in order to secure the movement ofthe shovels in the desired lines. The shovels c'an also be adjustedvertically independently of the front supporting-wheels and the lattermay also be adjusted, thus enabling us to secure the running of theshovels at any desired depth. The construction is also simple and can beeasily adjusted, as

described, by the operator in a Jfew moments,

not requiring the services of a skilled mechanic.
